SELF-OIEENING UMBRELLA.

Application filed September 12, 1921. Serial no. 500,238. 7

T all whom it may concern Be it known that I, SAMUEL S. Fnn'rz, Sn, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Self-Opening Umbrella, of -Which the following is a specification.

My invention consists of a self-opening umbrella or parasol provided with a cup in which the tips of the ribs may be contained, means for locking the runner, and means for releasing the tip cup and the runner, as will be hereinafter further described.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be 'va ried, and so it is to be understood that the invention is not limited to the specific details shown and described, but I reserve the right to such modifications as come within the scope of the claim.'

Figure 1 represents a side elevation of an umbrella in closed condition embodying my invention.

Figure 2 represents a side elevation of the frame of the umbrella in open condition.

Figures 3, 4:, and 5 represent partial longitudinal sections, and partial side elevations of portions of the umbrella on enlarged scales, certain members being in different positions in the three figures.

Figure 6 represents a transverse section on line 6-6 Figure 4.

Figure 7 represents a side elevation of a detached portion.

Figure 8 represents a transverse section on line 8-8 Figure 4:.

Figure 9 represents a side elevation of a portion of Figure 8-in a different position.

Similar numerals of reference indicate corresponding parts in the figures. Refen ring to the drawings.

1 designates the ribs, 2 the stretchers, 3 the runner and 4 the stick of an umbrella. On the lower portion of the runner is the disc or head 5 and the collar 6, said disc being stationarily connected with the runner, and said collar being movable over said disc and the adjacent portion of the runner. 50 A portion of the collar surrounds the disc and is of considerably greater diameter than the latter forming the cup 7 which is adapted when the umbrella is closed to receive the tips of the ribs and retain them 55 therein, avoiding spreading apart of the ribs, a feature of itself known in the art.

The inner end of the collar 6 is connected with the reduced cylindrical portion 8-which is slidable with the collar on the contiguous part of the runner 3, said portion having surrounding it opposite-to, said coliar- 6 the auxiliary tapered collar 9 which is connected with the runner and movable therewith. Its lower outer end is inturned forming the flange 10 which end is towards the stickof the umbrella. l I

In the head of the collar 9 is the slot 9* and on the adjacent end of the cylindrical part 8 of the tip cup is the'ton'gueS which is adapted to enter freely said slot so as to guide the tip cup in its motions and prevent rotation of the same. v

Near the handle of the umbrellaisthe rez sili ent catch 11 which is formed of a movable bar having in its side a plurality of shoulders such as 12 and 13whichare adjacent to each other, and the exterior operating finger piece-14', the catch being guided" in a slot in the stick as well known.

Interposed between the disc 5 and the cylinder 8 is the spring 15 whose tendency is to move the tip cup 7- from the disc 5, so as to release the tips of the ribs, see Fig ure 4, as will be hereinafter more fully described.

Attention is drawn to the fact that the I shoulders 12 and 13 are of different lengths, the shoulder 12 being the shorter, and that in closing the umbrella the collar 6 is drawn down with the runner. Then the ribs are folded inwardly and the tips thereof placed over the disc 5, when the collar 6 is moved by hand away from the handle and then let go when its cup surrounds the tips and prevents the ribs from opening out, see Figure 3. At the same time, the spring 15 is comopenmg of the umbrella, a feature of itself known in the art.

When the umbrella is to be opened, the

catch 11 is pushed in a suflicient distance, then the shoulder 12 slides inwardly on the .end of the tongue 8*, and clears said end when the tip cup is released." Then the spring 15 is permittedto expand whereby it 1 Then the'catch is pushed. in to full extent when the shoulder 13 clears the flange 10 i of the auxiliary collar, thus releasing the latter and consequently the runner, when the spring'employed to open the umbrella exerts its power onthe runner and draws on the latter so as to cause it to side onthe stick to open the stretchers and consequently the ribs, thus causing the self opening of the'umbrella. v r 4 In closing the umbrella .the runner is V drawn down by the collar, and the ribs are gathereduin so. that the tips are disposed to- Wards the runner when the tip cup Gis moved up so-that thecup'encircles the tips and controls them and consequently the ribs from outward motions. Then the end'of the tongue8 is'seated on the shoulder 12 of the catch 11, ,which latter has movedout by its resiliency,. and the spring 15 is comthe umbrella, said pressed Simultaneous therevvith'the flange 10 engages With the shoulder 13 of the catch and s0 locks the collar and consequently the runner, thus retaining the umbrella in closed condition and controlling the self opening spring from action, but When it is desired to again openthe umbrella the catch is oper V ated to release the tip cup and the runner in the manner set forth. I

Having thus described my invention What I claim as new and desire to secure ters Patent, 1s 1- by L In a self opening umbrella havinga run ner, a tip cup slidable thereon, means for releasing said tip cup, a tapered collar on the runner, a catch on the'stickr of theumfor retaining said tip cup in operative posi brella, said catchibeing provided With means tion, and-With means for engaging said 001- V lar for preventin tongue, and said collar having-ini'tsheada slot in which latter said tongue isslidable as a guide for the tip cup inits motions, and

serving to prevent rotation of thetip cup.
